InSAR (Interferometric Synthetic Aperture Radar) is a technique for mapping subtle ground deformation using radar images from Earth-orbiting satellites. With its global coverage and all-weather imaging capability, InSAR has become an increasingly important technique for studying volcanoes in remote regions such as the Aleutian Islands.

Early on the morning of May 18, 1980, the landslide swept into the upper North Fork Toutle River valley and came to rest within about 22 km of the volcano. The landslide deposit, however, was saturated with water, and contained snow and ice blocks from the volcano's former glaciers.

During the cleanup after the 18 August 1992 eruption of Mt Spurr volcano, Alaska. The population of Anchorage used mostly wet methods to clean up the ash, creating a peak water demand which resulted in water shortages and loss of pressure in some parts of the city due to bottlenecks in the distribution system.
